Anasim π-fpPower Integrity and Energy aware SoC Floor Planning
www.anasim.com
Methodology
Physics-based simulation with a high-degree of Abstraction
Resource and Layout planning starts at Architecture
Floor Planning and Energy Optimization are interlinked
Floor Plan and resource use refined with synthesis iteration
Benefits
Floor Plan correct by design and optimized for IP & SoC
Lowest possible power grid noise across the SoC
Lowest possible operating voltage for minimum energy
First-Si success greatly enhanced
